Wear-resistant ceramic material and preparation method thereof
The invention discloses a wear-resistant ceramic material and a preparation method thereof. The wear-resistant ceramic material comprises the following components in parts by weight: 65-70 parts of nano aluminum oxide, 10-15 parts of magnesium carbonate, 10-12 parts of kaolin, 5-12 parts of titanium diboride fibers, 5-8 parts of silicon carbide, 3-5 parts of sodium hydrogen carbonate, 5-7 parts of antimonous oxide and 3-5 parts of red mud. The invention further provides a preparation method of the wear-resistant ceramic material. The preparation method comprises the following steps: (1) weighing 10-15 parts of magnesium carbonate, 10-12 parts of kaolin, 5-12 parts of titanium diboride fibers, 5-8 parts of silicon carbide, 3-5 parts of sodium hydrogen carbonate, 5-7 parts of antimonous oxide and 3-5 parts of red mud and adding all the components into a high pressure homogenizer and uniformly mixing; (2) adding 65-70 parts of fully ball-milled nano aluminum oxide under an inertial atmosphere into the product obtained in the step (1), and raising the temperature to 700-710 DEG C to react for 1-2 hours; and (3) compressing and molding the product obtained in the step (2), heating to 1300-1350 DEG C at a temperature raising speed of 5 DEG C/minute, firing, insulating fro 2-4 hours, and cooling to obtain the wear-resistant ceramic material.
